FS: Six 3 1/4 x 4 1/4 Graphic Film Holders - $20

I found half a dozen 3.25 x 4.25 Graphic Film Holders, Type 5, from Graflex. All seem to be in excellent condition, with good looking darkslides and tight-looking endflaps. I have no use for them, so out they go!

Are these the slotted type that fit the RB Graflex cameras, or are they plain? (the slotted ones will have one slot running the length of each side, and one going across each side at the top near the darkslide slot).
